Allergen-specific B Cell (N/A)

Target: N/A
Molecular classification: B Lymphocyte, Immune cell

Overview

Allergen-specific B cells are a subset of B lymphocytes that recognize and respond to specific allergenic proteins. Their primary role in allergic disease is the production of immunoglobulin E (IgE) antibodies directed against components of allergens, which is central to the pathogenesis of immediate hypersensitivity reactions. They can be targeted by immunotherapies such as OIT.

Other names: Allergen-specific IgE+ B cellsAllergen-specific memory B cellsIgE+ B cells

Mechanism of action

Oral immunotherapy (OIT) modulates allergen-specific B cell activity, leading to reduced activation gene expression and altered antibody isotype production.

Biological functions
